AGITATOR.

T o all whom it 'may concern: Be it known that I, JOHN H. Gross, a citizen of the United States, resident of Red Wing, county of Goodhue, State of Minnev for agitating the liquid solution in the vault,

breaking up the fecal matter and positively and quickly reducing the contents of the vault to a semi-liquid state.

A further Objectis to provide a device ofthe class described which is easily accessible through the top of the vault and is of such construction that it can be folded for insertion into the vault or removal therefrom.

The inventionconsists generally in various Constructions and combinations, all as hereinafter described and particularly point. ed out in the claims.

In the accompanyingv drawings forming part of this specification,

Figure 1 is a view of a waterless vault with the wall of the vault broken away to show the position Of the macerator therein,

Fig. 2 is a sectional view through the macerator,

Fig. 3 is an end View of the same, with the middle portion broken away, showing the means for suspending the macerator in the top of the vault, y

In the drawing 2 represents the floor `of the toilet, 3 the toilet bowl having the usual cover 4 and vent 5. 6 is a pipe leading from the bowl to a vault 7 arranged preferably below the foundation wall 8 and having a manhole 9 and cover 10 on the surface Outside the foundation wall. In this vault I place a suitable quantity of a chemical solution, and for the purpose of breaking up and disintegratingthe matter in the solution I make use of the following described device which forms the subject matter of my invention.

This device, which I prefer to designate as a macerator, consists of a pair of base or lower bars 11 which are pivotally connected at 12 to a pair of upright bars 13 and a pair of inclined bars 14 connect the upper ends y specification of Letters Patent.

ofthe bars 13 with the bars 11,. thereby forming a triangular shaped frame. In the top of the vault is secured a strap 15 having depending ears 16 and bolts 17 pass through said ears and through the adjacent ends of the bars 13 and 14 and form pivotal supports for said bars on said ears and said bolts are held in place by suitable means, such as cotter pins 18. Vhen these pins are removed, the bolts may be Withdrawn and the bars detached from the ears to allow the frame to be folded or collapsed and removed from the vault through the manhole open-` ing 9. The insertion of the frame into the vault may be accomplished in the same way.

At the lower ends of the bars 13 I provide a blade 19 having a series of openings 20 therein and knives 21 formed by pressing the metal out of the blade 19. These knives and openings are preferably, as shown in Fig. 3,' approximately semi-circular in form, the knives beingV inclined slightly with respect to the vertical surface of the blade from which they are pressed. Said blade hangs vertically in the solution so that when the frame is Oscillated, the blade drawn through thesolution or semi-liquid will flow through the openin gs and the solid matter contacting with the knives will be broken up and disintegrated. At the lower ends of the bars 14 I provide a similar-blade 19at having openings .20a therein formedby pressing out knives 21a. This bladeis clined, forming substantially a continnuation of the bars 14 and the knives 21a act as beaters to break up the solids in the solution and thoroughly disintegrate the -Inatter therein.

A strap 22 is secured to the blade 19a andhas upwardly` turned ends 23 for attaching a rod 24 thereto which extends up through the pipe 6 and to a point near the closet-seat and is provided withl a finger Ioperating rod directly under the bowl and at a suitable angle to have immediate action on the fecal matter falling into the vault and the downward flail-like action of the blade operating in Aconjunction with the knives will quickly reduce the contents of the vault to a semi-liquid state. y

The knives are preferably set at an angle of about 45 degrees to the blades and their main function is to reduce the toilet paper to a pulplike condition and break up and disintegrate any solids in the solution. The blades are so constructed and their relative position is such that the stroke necessary for the proper reduction .of the solids need not exceed an eight inch maximum. Two points of connectionfor the rod with the macerator are shown, one near the lower end of the forward blade and the other in the rear of it. This' allows the closet bowl to be turned at any angle to the vault and still allow the to be practically verticall The number of openings in the blades and their size and shape are not of Vparticular importance and may be varied to suit different conditions, the particular features of the device being the manner of mounting it in the Vault, the position of the blades and their line of travel.

I claim as my invention:

l. The combination, with a closet vault adapted to contain a chemical solution, of an agitator suspended therein and comprising an oscillating frame and agitating blades carried thereby, and means for oscillating said frame.

2. The combination, with a closet vault adapted to contain a chemical solution, of an agitator suspended therein and comprising a frame, a rear blade vertically arranged in said agitator, a forward blade mounted at an incline therein, said blades having openings therein and means for oscillating said frame.

3. The combination, with a closet vault adapted to contain a chemical solution, of an agitator arranged therein and comprising a frame, blades mounted in angular relation in said frame and having openings therein, and means for moving said frame back and forth through said chemical solution.

4. The combination, with a closet vault adapted to contain a chemical solution, of an agitator arranged therein and comprising a frame, blades mounted in angular relation in said frame and having vopenings therein and knives formed on said blades and means for moving said frame back and forth through said solution.

5. The combination, with a closet vault adapted to contain a chemical solution and having a man hole and cover therefor, of an agitator comprising a folding frame pivotally supported in the top of said vault adjacent said opening and having removable pivot pins accessible through said opening and means for oscillating said agitator in said solution.

6. The combination, with a closet vault adapted to contain achemical solution, of a triangular frame pivotally supported in the top of said vault to oscillate therein, a rear blade mounted on the lower portion of said Y frame and having openings therein and knives adjacent said openings, a forward blade mounted at an angle to said first named blade and also having openings therein and knives adjacent said openings, and means extending upwardly through the top of said vault for moving said frame back and forth through said solution.

7. The combination with a closet vault adapted to contain a chemical solution and having a manhole and a cover therefor, of a folding frame having means for supporting it in the top of said vault for oscillation therein said means being located near said manhole for convenience of insertionor removal of said frame therethrough.

8. The combination, with a closet vault adapted to contain a chemical solution, of an agitator suspended in the top of the vault and depending therein and comprising an oscillating frame having means for agitating and disintegrating the solids in the closet vault, and means for operating said frame.

9. lThe combination, with a closet ,vault adapted to contain a chemical solution, of an agitator suspended in the top of the vault and depending therein and having freedom of movement forward and backward through said solution, said agitator being provided with means for separating and disintegrating the solids in said Solution, and means for operating said agitator.

ln witness whereof I have hereunto set my hand this 22nd day of April, 1918.
